Slight vibration when in park at idle

Noticed a very slight vibration that comes in waves when the truck is on and in park only. When I put it in drive it goes away, even at idle. I thought it was the AC compressor turning on and off or something so I turned everything off but it's still there. Anyone else notice this when idling in park?

yeah i do through the center armrest occasionally, same as you though in gear driving around smooth as silk

not really concerned, next time I notice it though will see if it stays the same when in neutral...

Waiting on the reply from @Oldfart on this one...

Mine has done the same since new. Don’t think it’s anything to be alarmed about.

It doesn't bother me just want to make sure it's not something that needs to be addressed or will get worse over time.

They are not the smoothest idlers, especially with the AC blasting.

Same on my 2020.

My old 2017 F150 felt like an electric car sometimes cause it was so quiet and numb while idling.

Mine did this after a day in the mud. I had some mud on the IC fans causing a vibration when they came on. FMIC from COBB fixed that.

Mine does the same thing after receiving mine a few months ago. Doesn’t really bother me but also want to make sure it’s nothing I need to be concerned about.

It happens to me once every few weeks also.
